This Digest gives guidance to professional engineers on the structural appraisal of existing buildings, including making a structural appraisal for a material change of use. Part 3 describes structural appraisal procedures. It looks in detail at the process of structural appraisal: at the steps involved, and at the levels of activity. It then goes on to consider structural work needed for a proposed change of use, at health and safety issues, and at reporting on the outcome of the appraisal. Annexes to this Part cover ancillary aspects of the appraisal (safety concepts, partial safety factors, target reliability values), and residual service life estimation.
